Problem video call from CME to CUCM

[nurhat19921]

Hello! I have some problems with SIP trunk between CME and CUCM. When I cal from cme to cucm audio works fine, but video do not work. When I call from cucm to cme audio and video works fine. Both phones are sccp cisco 8941. On cme i configured rtp payload-type cisco-codec-video-h264  97. From "debug ccsip messages" I see that cme and cucm negotiate video ports and addresses. But from "show voip rtp conn" command i did not see video ports and address. Please help me!

Hi,

Can you please share the output of debug ccsip messages of non-working video call? Also share show run.

Before changing the PT of h264, did you change the PT of fax-ack?

Hi!

Thank you for reply! I attached debug non-video call.

Hi,

SDP negotiation looks good.

Add following command under dial-peer 20000000;

dtmf-relay rtp-nte sip-notify sip-kmpl and see if it makes any difference.

Also share the output of debug ccsip messages of working video call.

I added the command dtmf-relay rtp-nte sip-notify sip-kmp, but whatever not video. I attached debug of successfully call.

Can you share the voice class codec 1 config, also if you can use codec transparent ?

For the working call, share the dial-peer which is being used.

Hi, Vivek!

Have you any ideas ?

Hi,

SDP negotiation of non-working call seems good and similar to working call.

Can you please check with asymmetric payload full command? Simply remove rtp payload-type command and add 'voice-class sip asymmetric payload full' command in both incoming and outgoing dial peer. Using debug voice ccapi inout, please ensure that call is hitting the desired dial peer in both inbound and outbound direction.

Hi, Vivek!

No results.

[Abhay Singh Reyal]

Share the debug ccsip messages with calling and called number. Also if you can make below change and see if that works or not.

no rtp payload-type cisco-codec-video-h264  97

rtp payload-type cisco-codec-fax-ack 111

rtp payload-type cisco-codec-video-h264 97

Make sure the binding is correct and if it is try to remove the binding and do it again.
